Here's your complete sports & fitness-focused Samsung Watch4 & Watch4 Classic in-depth review. In this review, I dive into all the new features aimed at sports/fitness/health, and then after that I dive into a slate of sports including running, cycling, hiking, and swimming to see how it performs for both GPS and optical heart rate accuracy.

This is the first watch to utilize the new Google + Samsung variant of Wear OS. This new operating system (or, slightly rebranded one) allows access to the Google Play store for apps, including Strava, Adidas, and many more previously unavailable or un-updated on Tizen.
